Embodiment 1
[0043] Example 1 : Compound of the present invention ( 1 ) preparation
[0044] Preparation of intermediates:
[0045] Will m- CPBA (17.2g, 1mol) was dissolved in dichloromethane (100ml), added to a solution of curcumol (11.8g, 0.05mol) in dichloromethane (100ml) at 0°C, and kept stirring at 0°C for 2 hours. After the reaction, the reaction liquid was extracted three times with NaOH (2 mol / l) solution, the organic phases were combined, extracted with water until neutral, and dried over anhydrous sodium sulfate. The solution was concentrated and evaporated to dryness, and the crude product was purified by silica gel column chromatography (cyclohexane:ethyl acetate=50:1~10:1) to obtain 11.95 g of white waxy solid 10,14-epoxycurcumol, yield 95% .
[0046] 10,14-epoxycurcumol (10.08g, 0.04mol) was dissolved in acetonitrile (600ml), and lithium perchlorate trihydrate (6.4g, 0.04mol) and diethylamine (20ml) were added at room temperature. The resulting mixture was heated t...
Embodiment 2
[0050] Example 2 : Compound of the present invention ( 2 ) preparation
[0051] The preparation of intermediate: the same Example 1 The preparation method of intermediates.
[0052] target compound ( 2 ) preparation:
[0053] Dissolve (1S, 4S, 5S, 7S, 8R)-5, 8-epoxy-9,10-ene-14-chloroguaiacol (27mg, 0.1mmol) in acetone (4ml) and add Nitrophenol (16.6 mg, 0.12 mmol), anhydrous potassium carbonate (20.7 mg, 0.15 mmol), potassium iodide (5 mg, 0.03 mmol). The resulting mixture was heated to reflux for 3 hours. The reaction solution was concentrated and evaporated to dryness, and the obtained crude product was purified by PTLC (cyclohexane:ethyl acetate=2.5:1, eluted with ethyl acetate) to obtain colorless oily compounds (1S, 4S, 5S, 7S, 8R)-5, 8 -Epoxy-9,10-ene-14-m-nitrophenoxyguaiacol ( 2 ) 26.1mg, yield 70%. The spectral data of the compound are as follows: MS(ESI) m / z : 396.0 [M+Na] + ; 1 H-NMR (300 MHz, CDCl 3 ) δ (ppm): 2.08 (1H, dd, J =6.4, 9.3Hz, H-1), ...
Embodiment 3
[0055] Example 3 : Compound of the present invention ( 3 ) preparation
[0056] The preparation of intermediate: the same Example 1 The preparation method of intermediates.
[0057] target compound ( 3 ) preparation:
[0058] Dissolve (1S, 4S, 5S, 7S, 8R)-5, 8-epoxy-9,10-ene-14-chloroguaiacol (27mg, 0.1mmol) in acetone (4ml) and add Nitrophenol (16.6 mg, 0.12 mmol), anhydrous potassium carbonate (20.7 mg, 0.15 mmol), potassium iodide (5 mg, 0.03 mmol). The resulting mixture was heated to reflux for 3 hours. The reaction solution was concentrated and evaporated to dryness, and the obtained crude product was purified by PTLC (cyclohexane:ethyl acetate=2.5:1, eluted with ethyl acetate) to obtain colorless oily compounds (1S, 4S, 5S, 7S, 8R)-5, 8 -Epoxy-9,10-ene-14-p-nitrophenoxyguaiacol ( 3 ) 31.7mg, yield 85%. The spectral data of the compound are as follows: MS(ESI) m / z : 396.0 [M+Na] + ; 1 H-NMR (300 MHz, CDCl 3 ) δ (ppm): 2.07 (1H, t, J =7.8Hz, H-1), 1.88 (...
